Personal Handyphone System (PHS)

“Providing Wireless Local Loop Connectivity”

Personal Handyphone System (PHS) has been in existence in Japan for years. In the mid-1990s, UTStarcom introduced two highly successful Wireless Local Loop (WLL) solutions that differed only in the core network and were based on the PHS standards and specifications. The first solution introduced was Personal Access System, or PAS™, followed by the IP-based Personal Access System, iPAS. The PAS and iPAS networks are a low-cost and easy to deploy wireless alternative to copper offering the flexibility of fixed, portable and mobile voice and data services concurrently. Today UTStarcom’s PAS and iPAS networks are widely deployed around the world.

UTStarcom's PAS solution is ideal for operators with existing circuit infrastructure and available capacity. The PAS product line offers service providers and mobile operators a low-cost alternative to offer mobility-based wireless service. Operating in the 1880-1920MHz spectrums, the PAS network is ideal for service providers with existing circuit capacity and access to radio spectrum. Utilizing a micro-cell topology, the PAS network is a low-cost, highly scalable, carrier-class solution offering the operator the assurance of rapid payback on its infrastructure outlay.

UTStarcom’s iPAS solution is the preferred cost-effective alternative for operators with a shortage of circuit capacity. Operators can migrate their current wireline network to an Internet iPAS network that provides wireless voice and data services within a city or community. The system enables service providers to offer new wireless services, such as citywide mobility, same-number wireless extension, email, mobile Internet access, short messaging, and location-based services. iPAS interconnects with the existing Public Switched Telephone Network (PSTN) by the Signaling System 7 (SS7) interface, making it an ideal solution for areas where either extra switching capacity or the V5.2 Next Generation Integrated Digital Loop Carrier (NG-IDLC) interface is not available.
